Abstract

INVERSOR TRIFÁSICO E MÉTODO DE CONTROLE PARA O MESMO. Um inversor trifásico e um método de controle para o mesmo são fornecidos. Capacitores ressonantes são fornecidos entre os pontos intermediários de três braços de ponte e os pólos positivo e negativo de um barramento DC para constituir unidades ressonantes com indutores de saída, de modo a estabelecer uma rede ressonante para a implementação de comutação suave, sem adicionar um transistor de comutação. Em comparação com o comutador suave do inversor trifásico na tecnologia convencional, os dispositivos de circuito são salvos, o processo de controle é simplificado, e as despesas gerais de hardware e software do sistema são reduzidas. Ao controlar o inversor trifásico para operar em um modo contínuo, a perda de comutação do transistor de comutação e a perda de condução de um diodo de retorno no transistor de comutação são reduzidos, a eficiência de conversão é melhorada, o ruído eletromagnético causado pelo transistor de comutação é reduzido e as correntes de rede de alta qualidade são emitidas.THREE-PHASE INVERTER AND CONTROL METHOD FOR THE SAME. A three-phase inverter and a method of controlling it are provided. Resonant capacitors are provided between the midpoints of three bridge arms and the positive and negative poles of a DC bus to constitute resonant units with output inductors so as to establish a resonant network for implementing soft switching without adding a transistor. switching. Compared with the three-phase inverter soft switch in conventional technology, circuit devices are saved, the control process is simplified, and the system hardware and software overhead is reduced. By controlling the three-phase inverter to operate in a continuous mode, the switching loss of the switching transistor and the conduction loss of a feedback diode in the switching transistor are reduced, the conversion efficiency is improved, the electromagnetic noise caused by the transistor switching time is reduced and high quality network currents are output.
